15.6 CICS monitoring

Next we cover CICS monitoring.

15.6.1 Single user

Start CICS monitoring on your CICS system if it is not already done by entering

transaction FBII. Run the transaction MYTD with user RB_DEMO, password

xxxx, company any other than IBM, and request the quotation (Option 1).

Start Application Monitor under ISPF and select Option C for CICS. The list of the

available systems is displayed. Select your system and press Enter. The list of

the transactions is displayed as shown in Figure 15-22.

You can compare this with the other versions of the Trader application, such as

the TDB2 transaction, as shown in Figure 15-25.

15.6.2 Monitoring the simulation

Look at the CICS transactions using Option C for CICS on Application Monitor

Main panel, select the CICS subsystem, and look at the transactions. For

transaction MYTD, the only difference between one user and the simulated

crowd of users is the value in the Count column.
